I have a Q500 4k. I crashed it a couple of weeks ago and replaced the shell. Once the shell was replaced I flew it a couple of times and it worked great. I took it on vacation down south and it will not stay powered up. I use a hobby charger to charge the batteries and all 4 batteries are fully charged with proper voltage. When I power up the Q I turn the ST10 on first and then the Q. The Q stays on for about a minute and then shuts down completely. I connected the Q to the GUI and I get a low battery warning as well as ESC's need to be rest. When I go to set the ESC's nothing happens. I switch off the Q and let it sit for a couple of minutes. When I switch the Q back on I get nothing. No lights nothing. When I let it sit all day and try it again it turns on for about a minute with the same issues.
